ANTIS KIDDING DEVICE.

Specification of Letters Patent. Patented Feb. 14;, 1911.

Application filed March 11, 1907. Serial No. 361,806.

To all whom it may concern:

Be it known that I, EDWIN B. S'riMrsoN, a citizen of the United States,residing in the borough of Brooklyn, county of Kings, city and State ofNew York, have invented certain new and useful Improvements inAntiskidding Devices, of which the following is a specification.

This invention relates to certain improvements in anti-skidding devicessuch as are adapted for use in connection with automobiles and the likefor application to the wheels to prevent skidding and to protect thetires thereof, and the object of the invention is to provide a device ofthis general character of asimple and comparatively inexpensive naturewhich shall be strong, durable and capable of ready application andadapted for effective engagement with the roadway for the protection ofthe tires and the prevention of slipping or skidding of the wheels.

The invention. consists in certain novel features and principles ofconstruction, and combinations and arrangements of the several partsofthe improved anti-skidding device, whereby certain importantadvantages are attained and thedevice is rendered simpler, cheaper andotherwise better ada ted and more convenient for use, all as wil behereinafter fully set forth.

The novel features of the invention will be carefully defined in theclaims.

In the accompanying drawings which serve to illustrate myinvention-Figure 1 is a perspective view showing an anti-skidding deviceembodying my improvements and adapted for application to an automobilewheel; Fig. 2 is a face view of the device as shown in Fig. 1; Fig. 3 isa view showing the device as viewed from the rear with the rear ply ofthe securing material removed; Fig. 1 is a sectional view takentransversely through the device as shown in Figs. 1, 2 and 3;.Fig. 5 isa perspective view of one of the individual members of the device asshown in Figs. 1, 2 and 3; Fig. 6 is a sectional view similar to Fig. 4,but showing a modified form of the individual members of the device.

As shown in these views the device embodying my improvements comprises aleather or other flexible band or strip bent on itself, the rear ply 2of which is secured to the front ply 4 by means of rivets 3, 3 so as toproduce loops 5, 5, at opposite ends of the device, with which areengaged metallic eyes 6, 6, for engagement with attaching means of anypreferred kind whereby the device ma be secured upon an automobile wheelor t e like with the central portion a of the strip or band extendedtransversely across the tread of the tire for effective engagement withthe road way as the wheel turns. V

The strap or band 1 may be formed from leather or other sufiicientlytough and flexible material, and upon the central part thereof aresecured metallic members 7 7 arranged in a series extended len thwise ofsaid strap or band. Each of sai elements 7, 7, is formed of a piece orstrip of metal extended transversely of the band or strap 1 with its endportions 8, 8 bent at angles so as to be adapted to extend over andprotect the edge portions of the band or strap to reduce the wearthereon and also to afford a secure engagement with the roadway in theturning of the wheels to which the device is applied.

In forming up the members 7, 7, the lateral edge portions 10 10 of eachblank are bent or struck up at right angles to the outer face of theblank, as seen in the drawings,

so as to be adapted, when the member is in place on the band or strap 1,to project at right angles to the face thereof for engagement with theroadway, the end portions of each blank being also bent rearwardly atright angles to the central part of the blank to produce the angular.endportions 8, .8, which take across and protect the edge surfaces of theband'or strap 1. v

The extremities of the blank, after having been bent at right-angles toproduce the edge protecting parts 8, 8, are bent toward each other asshown at 11, 11 and are adapted to .take behind the rear surface of thecentral part of the band or strap 1 and are held or housed between saidcentral ortion 1 and the lapped end portions 2, 2, in such a way as toeffectively prevent such movement of the members as would be calculatedto dislodge them from the band or stra When formed or struck up in thisway, t e inwardly directed extremities 11, 11 ofthe members 7, 7, aremade of greater width than the central or trough-like portion of saidmembers, whereby, when the members are slipped on in a series extendedlengthwise of the strap or band 1, the said wider extremities 11, 11will contact at the rear face of the central part 4 of the band or strapand will serve to hold the members in position with their road-bitingedges 10, 1O spaced apart for effective engagement with the roadway toprevent slipping or skidding of the wheels. The opposite edge portions12, 12 of the inwardly bent extremities 11,

11 of the members are turned upward toward the body portions of themembers, to adapt them to bind against the underside of the flexiblestrap when the latter is flexed to conform it to the rotundity of thetire. The upturned edges 12 therefore hold each tire-protective deviceagainst sliding along the straps or bands 1. When the members are inplace upon the band or strap 1, the rivets 3, 3, at the ends thereofwill serve to hold the series of members with said overturned edgeportions 12, .12 in contact and will also assist in holding said membersfrom slipping endwise along the band or strap.

Between the outwardly directed or flanged edge portions 10, 10, themetal of the body portion of each member is punched or bent outwardly ateach end of the member as seen at 14 to provide transverse lugs foreffective engagement with the roadway to prevent slipping or skidding.

From the above description of my improvements, it will be seen that theimproved anti-skidding device is of an extremely simple and inexpensivenature and is especially well adapted for use by reason of the ease andconvenience with which the device may be applied in position and of thesecurity and protection afforded by it both against skidding or slippingof the wheels and wear of the tires, the series of members 7, 7,aflording a metallic binding extended along each edge of the flexibleband or strap to prevent wear and cutting thereof, and it will also beobvious from the above description that the device is susceptible ofconsiderable change without material departure from the principles andspirit. of the invention and for this reason I do not desire to beunderstood as limiting my improvements to use in connection with thespecial arrangement and construction of the band or strap, nor do Idesire to be understood as limiting myself to the precise form andarrangement of the individual members as herein'set forth in carryin outmy invention in practice. For examp e, in Fig. 6 I show a modifiedconstruction of the individual members, wherein the central portion ofthe member, which lies at the outer face of the device, is apertured atits .I claim and desire to secure by Letters Pat'- ent is 1. In ananti-skidding device, the combination of a strip of flexible materialadapted to be secured transversely across the tread; metal membersextending across said strip with their ends underlapping the strip,andtheir sides upturned to form trou h-like road-biting edges; and astrip of flexible material secured under the first named strip, alsounder the underlapping ends of the metal members and adapted to protectthe tire from said underlapping ends.

2. In an anti-skidding device the combination of a strip of flexiblematerial adapted to be secured transversely across the tread; aplurality of road-engaging members connected with the strip and slidablelengthwise thereof; and stops on the strip confining the road-engagingmembers in a series between them.

3.
